Hi Michael. That is great you were able to find and fix the bugs.
I had some Maui "experts" who were nice enough to trouble shoot the issues with me on our Cluster - we made several changes to no avail. I created accounts for the experts on our HPC cluster and over several weeks period they eventually gave up as they could not figure it out. I too posted the issues but got very little traction/help at that time. For us, using Moab with no other changes, limit changes or anything else other modications other than changing the port and "maui.cfg" to moab.cfg" and using Moab fixed all of our issues. For us it was not a limit issue or any other obvious change. We came to the conclusion that it was internal bugs with Maui that were not easily fixed. I will say that GE user's group is tremendously helpful in comparison to Maui user's list. There is MUCH more activity with GE in the order of 100x more in comparison. Not trying to persuade or change anyone's opinion, but stating my own observations that may help others with similar issues.
